MX1 and myasthenia gravis: Starting from our LDA results and from the published data [14, 15], we selected six genes (IL-6, IFN-γ, HLA-DRα, IL-10, IFN-β, and MxA), expected to be dysregulated during inflammation and immune response, and analysed their expression by real-time RT-PCR on a higher number of MG and control thymuses, including EBV-positive MG thymuses and EBV-negative nonpathological thymuses [6].
